Standard Mail

Each piece of standard mail must weight less than 16 ounces. Anything heavier than 16 ounces must be mailed as package service or priority mail.

Reduced rates are available for mailing 200 pieces or more pieces of standard mail or a mailing of 50 pounds. The standards for size and surcharge rates for single-piece standard mail weighing one ounce or less are the same as for first class.
